 - avoid strong condition claims
 - do not infer turnkey condition from marketing text alone
 
+### Mandatory photo-review rule
+
+If an accessible all-photos view, photo grid, photo page, or fallback source exists, photo review is **required** before making condition claims.
+Do not silently skip photos just because pricing, comps, or carrying-cost analysis can proceed without them.
+
+The final assessment must explicitly include one line in the output:
+- `Photo review: completed via <source>`
+- or `Photo review: not completed`
+
+If completed, briefly summarize the condition read from the photos.
+If not completed, mark condition confidence as limited and say why.
